8 Claims. (Cl. 4-187) This invention relates to improvements in sinkmountings for installing a standard flat flange-type sink, or similarmember, in an opening in a drain board, cabinet top or like supportingstructure.

In modern kitchen installations where a flat flangetype sink, or similarmember, is provided which is to be mounted in an opening in a drainboard, cabinet top, or like supporting structure, the mounting meansgenerally provided comprises a sealing ring or molding strip ofgenerally T-shaped cross section, which is adapted to be positionedbetween the edge of the sink llange and the edge of the drain board inoverlapped relation with respect to the sink tlange and the top of thedrain board, and a plurality of adjustable clamping members, which areadapted to be positioned beneath the sink and the drain board to rigidlysecure the sealing ring in such relation as to provide a water-tightseal between the sink and the drain board. In order to facilitate theinstallation of the sink and to insure that the sealing strip will beproperly located with reference to the sink ange, it has been founddesirable to provide for initially assembling the sealing ring in properrelation to the sink ange and for connecting the same to the sink ange,so that the sink and the sealing ring may be inserted as a unit in theopening provided in the supporting structure.

It is an object of the present invention to provide a sink mountingmeans of the type described wherein means is provided for initiallyclamping the sealing ring or molding strip to the sink ilange, prior toinstallation of the same as a unit in the aperture in the drain board.

It is another object of the invention to provide a sink mounting meansof the type described and means for initially attaching the sealingstrip or molding frame to the sink rim which comprises a plurality ofclamping members adapted to interlock with depending portions of themolding frame adjacent the corners of the sink and to engage in frameclamping relation beneath the sink rim.

It is a more specific object of the invention to provide in a mountingmeans for a at rim-type sink, or similar member, which comprises amolding frame of generally T-shaped cross section having a top portionadapted to overlie the sink rim and edge of the drain board, or cabinettop structure, in which the sink is positioned, and having a dependingstem or web portion adapted to be positioned in the space between theedge of the sink rim and the edge of the opening in the drain board, aplurality of clamping devices for inititially securing the molding frameto the sink rim, whereby the sink and the molding frame may be installedas a unit in the drain board or cabinet top, the clamping devices eachcomprising an elongate plate-like member having an adjusting screw inthreaded engagement in an aperture intermediate the ends thereof andhaving an edge formation extending along each end thereof which isadapted to engage in interlocking relation with a shoulder formationalong a lower edge of the depending stem portion of the molding frame.

These and other objects and advantages of the invention will be apparentfrom a consideration of the preferred form thereof which is shown by wayof illustration, in the accompanying drawings, wherein:

Fig. 7 is a bottom plan view of the sink and molding frame completelyinstalled in the apertured drain board and secured in final clampedposition therein; and

Fig. 8 is a section, to an enlarged scale, taken on the line 8-S of Fig.7.

Referring to the drawings there is illustrated a sink 10 and a moldingframe assembly 11 which is adapted to be attached to the sink 10 priorto its installation in the aperture 12 in a drain board 13, the sink 10being assembled with the frame 11 and the latter being clamped to thesink ange 14 while both members are in inverted relation. rThereafterthe assembled unit is inverted relative to the position shown in Fig. land inserted in proper position within the drain board aperture 12.

The sink 10 is the standard type having an outwardly directed top rim orflange structure 14 and having rounded corners. The drain board 13 is aconventional linoleum covered plywood structure which may be a cabinettop or other supporting surface and which is provided with the aperture12 of the proper size and shape to receive the sink 10 and the moldingframe assembly 11.

The molding frame assembly 11 comprises a sealing ring or molding framemember 15 of one-piece construction, preferably of extruded metal, whichis adapted to be positioned around the periphery of the sink ilange 14with one side or top portion 16 overlying the top surface of the sinkflange 14 and with the other side or top portion 17 extending inoverlying relation to the adjoining top surface of the drain board 13.The sealing ring 15 includes a depending web or stem portion 18 which isadapted to be positioned in the space between the outer edge of the sinkflange 14 and the edge of the drain board 13 which surrounds theaperture 12. The sealing ring web or flange 18 is provided along itslower inner edge with an inwardly extending thickened portion orshoulder formation 19 having a bottom face 20, an inner face or sideedge 21 and a top face or edge 22, the latter extending at a slightangle downwardly towards the main portion of the web 18 so that anupwardly facing hooklike formation is provided along the bottom edge ofthe web 18. The depth of the web 13 is sufficient to bring the bottomedge 20 approximately on the level with the bottom edge of the drainboard 13 in which the sink is mounted and below the bottom surface ofthe rim 14 of the sink 10.

When installing the sink 10 in the drain board 13 it is desirable,particularly in the case of cabinet tops, to be able to lirst attach thesealing strip or molding frame 15 to the ange or rim 14 of the sink 16with the sink 10 and the sealing strip 15 in the inverted position withrespect to the final location of the same in the drain board 13 so thatthe sink 10 and the sealing strip 15 may be properly located withrespect to each other, and the sealing strip 15 may be readily clampedto the sink flange 14 to retain the same in the proper relation tothesink and to permit the insertion of the sink 10 and the sealing strip 15as a unit.

A plurality of molding frame attaching or clamping members 23 (Fig. 5)are provided for initially attaching the molding frame 15 to the sinkflange 14. The attaching members 23 each comprise a metal plate or stripcut to the shape shown in Fig. 5 and having the opposite end edges 24and 25 extending in right angle relation to each other. The end edges 24and 25 are bent or shaped to provide hook-like flanges 24', 25' whichare adapted to interlock with the hook-like shoul der formation 19 onthe inner end of the web 18 of the molding frame 15. A threaded aperture26 is provided intermediate the ends of the plate member 23 forreceiving the clamping screw 27. Four of the attaching members 23 areadapted to be positioned on the frame member 15, one at each of the fourcorners of the sink with the end ange formations 24', 25 in interlockingengagement with the shoulder formation 19 on the web 18 of the framemember 15, and to be clamped in fixed relation thereto by taking up onthe screw 27 which engages at its inner end beneath the ange 14 of thesink 10.

After the sink 10 and the molding frame 15 are connected the resultingunit is positioned in the aperture 12 in the drain board 13 as shown inFig. 6. Thereafter, a plurality of clamping elements 30 are arranged inspaced relation around the periphery of the sink ange 14 for securingthe molding strip 15, the sink 1l), and the drain board 13 in assembledrelation.

The clamping elements 30 each comprise a generally rectangular plate orbody portion 31 having at one end thereof a threaded aperture 32 and aclamping screw 33 which is adjustably secured therein. Intermediate theends of the plate 31 there is provided an upstanding hook-like formation34, the undersurface 35 of the hooked end of which is beveled, ordownwardly sloping, for cooperation with the top surface 22 of theshoulder 19 on the bottom of the web 18 of the molding frame 15. Theclamping elements 30 are arranged with the opposite end of the plateportion 31 extending beneath the drain board 13 and flange 14 of thesink 10 as illustrated in Figs. 4 and 8. The hook or groove formations34 on the clamping elements 30 are so constructed that the elementspivot about the shoulder or rim 19 on the bottom of the web 18 whenengaged therewith. The apertured end of each of the elements 30 extendsbeneath the flange 11 of the sink 10 and the opposite end extendsbeneath the drain board 13.

After the elements 30 are properly positioned in engagement with frame15 the adjusting screws 33 are taken up to clamp the elements inposition. The screws 33 tend to force the flange 14 into snug relationwith the inner top portion 16 of the sealing ring 15 and also to forcethe opposite ends of the elements 30 into clamping relation with thebottom of the drain board 13 and the outer top portion 17 of the moldingstrip 14 into tight engagement with the top of the drain board 13. Themolding frame 15, together with the frame attaching and clamping members23 and 30 may be provided as a kit for use when the sink 10 is installedin the aperture 12 of the drain board 13. The kit permits the moldingframe to be initially assembled with the sink and the assembled unit tobe readily installed, either in the shop, or in the field, greatlyfacilitating the installation of the sink in either location.

While specific details of construction have been referred to indescribing the illustrated form of the invention it will be understoodthat other details may be resorted to within the spirit of the same.Also, the mounting herein disclosed may be employed for securing in anapertured support a range unit or other member having a flanged edge orrim of the same general character as the ange of the sink illustrated.
